Polyethylene Glycol

Polyethylene Glycol


Polyethylene glycol (PEG) is a synthetic, hydrophilic, and biocompatible polyether also known as poly(ethylene oxide) or poly(oxyethylene). PEG refers to materials with molecular weights less than 20000 g/mol, while PEO refers to compounds with molecular weights greater than 20000 g/mol. Many organic solvents, including ethanol, acetonitrile, toluene, acetone, methylene chloride, hexane, and chloroform, are soluble in PEG polymers.

PEG is a non-toxic, flexible polymer that is widely utilized in biomedical research for drug administration, tissue engineering, bioconjugation, and surface functionalization. PEGylation is the non-covalent attachment or linking of PEG molecules to molecules, nanoparticles, and particles. PEGylation can improve the pharmacokinetic features of biological pharmaceuticals (e.g., peptides, proteins, oligonucleotides) and particle delivery systems by providing "invisibility" and biocompatibility. PEG hydrogels are made by cross-linking bifunctional PEGs and are extensively utilized in tissue engineering for controlled drug release and scaffolding.

Alfa Chemistry provides a diverse spectrum of well-defined PEG products for biomedical research applications, including a variety of molecular weights, end functionalities, reactivities, and polymer topologies.
